UNITED STATES DEMOUNTABLE HUT.

GEORGE BULBECK, OF LONDON, ENGLAND.

Application filed November 6, 1926. Serial No. 148,728.

This invention relates to huts, cabins and the like which are capable of being readily erected and disassembled for further erection.

The object of my invention is to provide a form of temporary structure of this type which will not involve the useof complicated parts necessitating skilled labour for their assemblage, and which will be of avery durable nature.

According to this invention the walls and root of a hut like structure consist of a number of sheets of metal or other suitable material provided with devices for attachment to bar or rod like frame members which are ar ranged to form a skeleton of the completed structure, the said sheets being arranged so that they extend partially over each other and having projections for engagement with each other.

An important feature of my invention consists in the sheets of metal or other suitable materialwith which to cover the surfaceso't the walls and roots of the building. These sheets are formed in suitable sizes and I find a useful size to be about 6 ft. X 2 ft. 6", and at the back ot each sheet is secured by rivets or otherwise two strips of wood running the length of the sheet and fixed so as to converge towards each other atter the manner of two sides of a baseless truncated triangle.

These sheets are so arranged that when they are put together longitudinally the narrowed and converging ends of the strips of wood upon one sheet can enter and be wedged comfortably into the wider spaces of the strips of wood upon the adjoining sheet. Allowance is made that the thin sheets of metal or other material can be made so as to cover joint vertically by the end of one sheet entering a short distance under the wooden strips ot the adjacent sheet, and if necessary the underside of the strips of wood may be re bated "for a short distance for this purpose. By means of these wooden strips upon the sheets of metal these are stiffened so as to be easily handled and they can be longitudinally attached to each other with case. With regard to the vertical superimposement of one sheet upon the other these will cover the joint up to the distance where the wooden strips do not reach the top or bottom of the sheet.

In constructing the whole of the building,

a stout wooden bearing is laid on the ground to cover the entire outline of the walls to be erected and these hearings are supplied with fixed iron shoes at certain intervals capable of receiving vertical metal pipes or stanchions which act to form the constructiveparts of the building.

Horizontal connections are arranged at the top of these pipes or stanchions at theeaves of the building "for securing the stiffness of the vertical supports and also for carrying the inclined pipes or stanchions from each of the eaves bearings upon which the roof is constructed. It will readily be understood that the constructional ironwork of the building can be braced together or supported in any ordinary and well known manner. i j

The improved sheets to which I have bet'ore referred are used to form the sloping sides of the root in the same manner as the vertical sides of the walls.

Angle pieces to keep out the weather can be arranged at the junction of any two walls and also a V-shaped metal piece placed upon the junction of the two sides of the roof acts as a ridge piece.

The metal sheets are attached to the constructional ironwork by means of a suitably hinged device, one portion of which is permanently attached to the wooden strips at the end of one plate and therefrom a bent hinged arm is provided so as to comfortably grip round the pipe or stanchion and then continued so that the free end can be re movably bolted, screwed, or otherwise securd to the wood work of the adjoining sheet, and this method of attaching the plates to the constructional work of the walls is also applicable to thereof. 7 1 I i In order that my invention may be clearly understood and readily carried into effect I have appended hereto three sheets of drawings somewhat diagrammatically illustrating an embodiment of same, wherein Fig. l. is a plan View of the ground frame for receiving the vertical stanchions.

. Referring to the drawingsthe bearing for supporting the hut frame consists of a stout rectangular wooden frame constituted by a plurality [of bars 1 united end on end. In Fig. '10 is shown a suitable method of unit ng the bars l'which consists in forming each end of each bar with a step 2 which overlaps a similarstep on the adjacent bar, the step at one end'of a bar being formed inthe upper face of the bar and the step at theother end being 'formedin the lower face of the bar.

A metal shoe 3 isse'eured' in the lbw'erstep 2, and this shoe is threaded to receive the lower andthreaded end of one of a number of vertical stanchions i. Upon each stan- ,chion t is secured a 'back nut 5 which serves as an abutment to ensure that all of the stan chions 4 are threaded corresponding distances into the bars 1, and further it brings the two overlapping portions 2 of the bars 1 close against each other.

Thefluprlghts or stanchions 4. are erected at .eachcorner of the base frame 1, and intermediatethe corners if the predetermined size of the hut makes such additional stanchions necessary.

" When the requisite number of Qstanchions tare erected the side or wall plates 6 (see Fig.

i are applied to the stanchions. Each plate 6 consists of a thin metal or other suitable sheet to the back face ofwhich are secured a pair of stifieningbars 7 preferably of Wood, permanently secured to the plate 6. The bars are symmetrically slightly out of parallel with the longitudinal edges of the plate 6, and the bars on all ofthe plates 6 correspond exactly-in their location upon their plates,

the distance between the inner opposing edges of the bars 7 at one end of a plate being such that they will receive as a nice fit between them the equivalent of the other ends 'ofthe bars 'on another plate 6. To enable the ends of the plates to overlap the ends of the bars 7 are rebated or recessed on their innerfedges as shown at 8 in Fig. 4. r

The plates Gare readily detachably secured to the stanchions 4 by means of clamps 9, a pair being secured to each bar 7. Each of these clamps 9 comprises a back plate 10 (see Fig. 6) which is permanently secured tothe bar 7 and has pivotal'ly connected to it an arcuate resilient metal strip 11,the free end of which is formed with 'a slotted lu 12 to receive a screw 13 pivotally connectecf to the back plate 10 and provided with a wing nut' have been secured to thestanchions 4 to maintain them rigid therafter members 16 are secured to the upper ends of the stanchion's i; The rafter members 16 and the stanchions i are preferably metal gas piping of standard diameter, and it is preferred to have a V or gable roof, consequently 'stanchions 4 which extend to or in juxtaposition to the apex of the roof are largerjthan the others. .The rafter members 16-are attached'jto the upper ends of the stanehions 4 by inverted .U

shaped brackets 17 (see Figsfili and "12) which are radiused to 'fit snugly over the bracing stays 19 can be connected across the members 16 and receive between their limbs 1 the upper ends of the stanchions 4, bolts18 corner or centre stanchions {i to brace upthc structure, and this can be effected conveniently by forming the ends of the stats 19 with hooks 20 to engage over selected olts 1 8 of the brackets 17 i :The roof is obtained "byaaxin a the rafter members 16a number of plates ti inthe same manner as the lates 6. and attached to the stanchions 4, an if desiredfs cial apex plates 21 (Fi 15) can be provide for bring. ing the gap To obviate horizontal spaces between the plates 6 the lower edge of each plate 6 is preferably slightly stepped, as indicated; at .22

(Figs. 7 and 15) to enable the plates tooveredge of the plate, and shorter stiffening bars 25 at right angles to the upper edges oft-he iii;

etween the upper edges of the,

plate, each of the bars having a clamp 9 for engagement with the rafter members 16.

To seal the vertical corners of the structure L section metal bars 26 are provided (Fi 8) which are engaged under the rebated ends of the stiffening bars 7 A door can be provided by having shorter plates 6 for one end or side of the structure, and providing a special vertical stanchion 27 (Fig. 7) to support one end of such shorter plates. A door frame 28 can then be fitted into the opening provided, such door frame having pivotally connected to it the door 29 (Fi 8).

The inner ends of the rafter members 16 are secured to each other by a number of pairs of plates 30 (Figs. 13 and 14), each pair of plates 30- and the ends of the members 16 having apertures 31 to receive bolts, bolts 32 being passed through further registering openings in each pair of plates 30. The plates 30 are preferably pentagonal metal members as shown in Fig. 13.

While I have referred to my improved p ates as being made preferably of sheet metal with stiffening pieces of wood at the baek so arranged as to be the connecting med1ums bet veen the two plates, it will be readily understood that the plates may be stamped or pressed out with grooves and projections which would be equivalent to fixing a Wooden piece at the back of the plate, and in this modification of my invention the whole plate would in one piece and the pressed out portion would also help to stiffen the plates.

When a floor is required for the building it is constructed and put together with sheets in the manner referred to upon suitable plates laid on the ground.

Space can be so arranged in the whole building construction so as to allow for the fitting where required of the necessary windows and doors with frames of ordinary con struction.

it will be readily understood that a construction this type can be quickly erected and also quickly dismantled and packed for removal to another site and the plates may be formed of any suitable material for the purpose.
